Looking further into the referenced paper, we see:

PROCEDURE Set_lnitiaI_Seed (S1, S2 INTEGER);Resets the initial seed of generator 1 to the values S1 and S2, which must satisfy: 1 <= S1 <= 2147483562 and 1 <= S2 <= 2147483398. The initial seeds of all other generators are recomputed accordingly, and all generator’s states are reset to these initial seeds. This procedure is called automatically at the beginning of program execution, with (default) parameter values S1 = 1234567890 and S2 = 123456789.
